Appears they want you to send them your cam sensor for proper rehab, if possible.
I get it. When your looking for an oversized bushing due to having spun in the lower body, there are many different levels of wear?
I guess your on your own in sourcing this bushing.
If you have access to CNC equipment or lathe, you can make your own bushings out of oil lite bronze. Many companies sell oil lite, try to pick OD based on what size you need.
